Struts : html:select

I have a combo box which is filled by a method in bean. I call the method in <jsp:iterate collection="<%=beanname.methodname()%>. Now on change I submitthis page and getthe value selected. Actually the property which I take in select contais a concatenated value. I set them explicitly in action class. But when I use <logic resent> to check the value setfor id to show thatcombo box selected it is getting.

I only want the selected value in combo to be shown as selected in the selectbox.
